Same fridge in both pics, just different covers. I own the MT35 ARB and use the Engel cover. It seals better than the older ARB one does.
Good luck in you search. I tried for a while to find the older ARB model, but never did. I like the classic look of the ARB one.
My one complaint with the Engel cover is that you have to sort of pull it back to get to the latch. I've learned to live with it.
